Which gas emission regime dominates within persistent lava lakes?

💡 Explanation

Open system degassing determines emission; because magma convection allows continuous gas release rather than pressure buildup. Therefore, continuous background flux dominates, rather than volatile accumulation causing fluctuations from fractional crystallization inside vesicles or local impermeable blockage.
